A new ligand, N,N-BIS (6-metyl-2-pyridinecarboxylamide-N-oxide)-1,2-ethane (L) and six lanthanide(Ⅲ) complexes (RE=La, Sm, Eu, Tb, Gd, Yb) were synthesized and characterized in detail. The results indicated that the ...
The crystal structure of cryptand L was determined via X-ray diffraction analysis.Four solid(cryptates) of cryptand(L) with M(Ⅲ) nitrates(M=Sm,Eu,Tb,Dy) were prepared and characterized by means of fluorescence spectr...
